I received this from an acquaintance who traveled to Portugal in the past. "19 1/4K" refers to "19-karat gold," which is commonly used in Portugal. There are two ways to express gold purity: parts per thousand and parts per 24. For example, 21.6-karat gold in the 24-part system is equivalent to "21.6 ÷ 24 = 0.9 (90.0%)" in the parts-per-thousand system. Similarly, 19 1/4K gold is equivalent to "19.25 ÷ 24 = 0.802 (80.2%)". Since I received this a while ago, the inspection was also done some time ago, and I don't have images currently. However, this product was also examined with an X-ray inspection machine, and a gold purity of 75-80% was clearly detected. Depending on the angle and location, the composition sometimes barely reached the level of K18, but for the sake of avoiding complaints, I've stated it as 75-80%. Also, although small and barely visible, I can confirm a hallmark with the number "800" and a deer on it with a 10x magnifying glass. The overall design is delicate and beautiful. While it's not high jewelry, both the pendant and the necklace have volume, so this single necklace will beautifully adorn your neckline. Filigree is a common design in Portugal, and it's a popular design that has been sold for a long time on GSTV (a Japanese jewelry TV shopping channel). In my subjective opinion, I've never seen anyone wearing authentic filigree, so you're unlikely to see anyone else with the same piece. Why not take this opportunity to purchase it? Pendant width: Approximately 2cm, height: Approximately 4.5cm (including the bail) Necklace length: Approximately 40cm * Please refrain from purchasing for resale purposes. * I do not know the weight as I do not have a scale. * Please refrain from purchasing if you are sensitive to used items. * The product overall looks quite clean, but since I haven't polished it, I've marked it as "slightly scratched or dirty" to avoid complaints.
